▎ 摘　　要

NOVELTY - A polymer composition comprises sulfonated graphene oxide, sulfonated carbon nanotubes and a base resin. USE - Polymer composition is used for forming hydrophilic separation membrane used as ultrafiltration membrane, microfiltration membrane, hollow fiber membrane, nanofiltration membrane (all claimed) and reverse osmosis membrane. Uses include but are not limited to domestic wastewater treatment, industrial wastewater treatment, ultrapure water production and seawater desalination. ADVANTAGE - The hydrophilic separation membrane obtained using the polymer composition has high mechanical strength and porosity, and excellent water permeability, hydrophilicity and antifouling property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for hydrophilic separation membrane, which is prepared using the polymer composition.
